1 Claim. (Cl. 292-216) This invention relates to a latch, pivotally-mounted in a bracket and positioned to receive a free or swinging edge of a door whereby, in the opening movement of the door, the edge of the door engages a knob that swings a bumper on the end of an arm over the surface of the door opposite to that engaging the knob, whereby the bumper holds the door, preventing return movement thereof, until the bumper is actuated manually to release the door.

The purpose of this invention is to provide a door stop that is automatically actuated, by the opening movement of a door, to swing a catching element over the edge of the door to prevent return movement of the door.

Various types of door stops and catches have been provided, and although many of such devices grip and hold a door, such devices are relatively complicated and costly to manufacture and are very seldom used. With this thought in mind, this invention contemplates a door stop and catch that receives a swinging edge of a door and that is actuated by the door to retain the door in the open position.

The object of this invention is, therefore, to provide a door stop that is actuated by the opening movement of a door to grip and hold the door in an open position.

Another object of the invention is to provide a combination door stop and catch that is designed to be installed by the average layman.

Another important object of the invention is to provide a combination door stop and catch that is designed to be installed for use on doors now in use without cutting or otherwise changing the door.

A further object of the invention is to provide a combi-.

nation door stop and catch which is of a simple and economical construction.

With these and other objects and advantages in view, the invention embodies an arm, having knobs on one end and a bumper on the opposite end, and a bracket for pivotally-mounting the arm, whereby in an opening movement of a door, the door engages a knob at one end and swings the arm so that a bumper on the opposite end extends over the outer surface of the door for retaining the door in an open position.

Other features and advantages of the invention will appear from the following description, taken in connection with the drawing, wherein:

Figure 1 is a plan view of the improved door stop and catch, showing the parts in positions wherein the door is engaging a knob of the catch.

I Figure 2 is a view, similar to that shown in Figure 1, showing movement of the door continued whereby the knob is actuated to swing the bumper against the outer surface of the door.

Figure 3 is an end elevational view ofthe improved door stop and catch, showing the device mounted on a horizontal arm of a bracket whereby the door stop and catch is supported above a rug or carpet.

Figure 4 is a cross section through the supporting arm,

taken on line 4-4. of Figure 3, showingan. elevational U-shaped bracket 14, in which arm 10 is pivotally-mounted by screw 15 extended through upper bar 16 and having threaded lower end 17, which is threaded into floor 18; and bar 16, supported by posts 19 and 20, having lugs 21 and 22 extended from rear surfaces thereof and provided with screws 23 and 24, which are threaded into floor 18.

The bracket may also be mounted on horizontallydispos-ed arm 25 of L-shaped support 26, which is secured to mop board 27 around the lower edge of a wall of a building, by screws 28; in this design, lugs 21 and 22 are secured to arm 25 by screws 29, heads 30 of which are positioned in countersunk openings 31, and arm 10 is pivotally-mounted on screw 32, which extends through bar 16 and is provided with head 33, which is positioned in countersunk opening 34, in arm 25.

As illustrated in Figures 3 and 5, knobs 11 and 12 extend upwardly from arm 10, and bracket 14 is positioned so that in the opening movement of door 35, the door engages knob 11 and the pressure of the door moves the knob toward bracket 14, swinging bumper 13 from the position shown in Figure l to that shown in Figure 2.

A bracket is positioned on a floor, and in spaced relation to a wall against which a door opens, whereby the bracket is out of the path of persons passing through the doorway.

Bracket 14 may be attached to a floor by screws 23 and 24, or to horizontal arm- 25 of bracket 26 by screws 29. Bracket 26 is positioned to support bracket 14 above the surface of rug or carpet 36 and also above linoleum or silencing pad 37 positioned on floor 38 below the rug.

The parts may be made of plastic or other suitable material, and the knobs and bumper may be coated to prevent marring or scratching a door or the like.

It will be understood that modifications, within the scope of the appended claim, may be made in the design outwardly thereof at right angles thereto, screw members 7 extended through said apertured lugs to secure said inverted U-shaped bracket to the horizontally disposed portion of said support, an arm positioned within said inverted U-shaped bracket, said arm having a pair of vertically disposed knobs extending laterally from one end thereof and a vertically'disposed bumper on the opposite end thereof, a bolt extended through the bight of said inverted U-shaped bracket, throughsaidgann intermediate of thepair of knobs thereon and, into the horizontally disposed portion of said support to pivotally mount said arm in said inverted U-shaped bracket, said support being.

adapted to be mounted so that one of the knobs is in the .path of a free edge of a door, with the knobs positioned I whereby the arm will swing below the free edge of the door and upon. engagement of one of the knobs by the 2, 976,07 1 3 i 4 free edge of the door, the arm is actuated to swing the References Cited in the file of this patent bumpei' against the Side of the door opposite to the side which engages the knob, the free edge of the door engag- UNITED STATES PATENTS ing the knob at a point spaced from the pivotal mounting 436,809 Shipsey Sept. 23, 1890 ofthe arm and hetween the pivotal mountingof-thearm 5 1,498,025 Franck June 17, 1924 and the pivotal mounting oflthedoor. 2,189,274 Storrs Feb. 6, 1940
